bun: I will try to find time to update my synergy howto post that I linked to in my previous post. One thing I forgot to mention was that I needed to add the name of my pc to the /etc/hosts file on my 770 to get it working.
I also now have this working wirelessly from my OS X ibook which is very cool.
I just checked gnumeric and entering data and editing using F2 all works as expected. Maybe I'll try and create a wiki page on maemo.org.
